Would it bother you if they taught Jesus was a cool dude like Budda and we can get to heaven on our own? Would you still think their baptism valid?
I support the decision. Gods commandments matter. Not being "tolerant enough", in time or being trendy. These kind of matters shows the importance of being true to the traditions and not bargain at all.
I am not understanding your point. Which tradition connects sexual morality to valid baptism?
A denial of the Deity of Christ would be problematic. My fairly uneducated guess is that such a group's baptisms would not be valid. But that's not really on the same level as gay "marriage" (which, as you will see if you read my previous posts, does in fact "bother" me).
If Protestants, who by and large teach the filioque, a completely heterodox ecclesiology, a false understanding of the nature of Grace, a different source of revelation, a heterodox understanding of the nature and conditions of salvation, etc., etc. can have their baptisms recognized, I'm not sure why a heretical and immoral understanding of marriage should break the came's back.
